the Configuration Register; therefore, the device may or may not return to the Comparator Mode
depending on the setting of the NVCMP/INT bit in the Nonvolatile Configuration Register.
Figure 5-2 illustrates both the active high and active low ALERT pin response for a sample
temperature profile with the device configured for the Comparator Mode and a Fault Tolerance
Queue setting of 2.

Interrupt Mode
Similar to the Comparator Mode, when the device operates in the Interrupt Mode, the ALERT pin
will go active if the measured temperature meets or exceeds the high temperature limit set by the
THIGH Limit Register and a valid fault condition exists (the consecutive number of temperature
faults has been reached). Unlike the Comparator Mode, however, the ALERT pin will remain
active until one of three normal operation events takes place: any one of the device’s registers is
read, the device responds to an SMBus Alert Response Address (ARA), or the device is put into
Shutdown Mode.
Once the ALERT pin returns to the inactive state, it will not go active again until the measured
temperature drops below the low temperature limit set by the TLOW Limit Register for the
appropriate number of consecutive faults. Again, the ALERT pin will remain active until one of
the device’s registers is read, the device responds to an SMBus ARA, or the device is placed into
the Shutdown Mode.
After the ALERT pin becomes inactive again, the cycle will repeat itself with the ALERT pin going
active after the measured temperature meets or exceeds the THIGH Limit Register value for the
proper number of consecutive faults.
This process is cyclical between THIGH and TLOW
temperature alarms (e.g. THIGH event, ALERT clear, TLOW event, ALERT clear, THIGH event,
ALERT clear, TLOW event, etc.).
In order for the ALERT pin to normally become active for the first time in the Interrupt Mode, the
first event must be a THIGH temperature alarm event.
Therefore, even if the measured
temperature initially starts off between the THIGH and TLOW limits and then drops below the TLOW
